specification of Letters Patent.

Application filed September 29, 1920. Serial No. 413,580.

To all whom it mag concem:

Be it known that IsHAM S. DICKEN, a citizen of the United States of America, residing at St. Louis, State of Missouri, has invented certain new and useful Improvements in Hinges, of which the following is a specification.

The object of my invention is to produce a hinge in which the leaves are adjustable relative each other. In the use of a conventional hinge on a heavy door such as that on a refrigerator car since the leaves are not adjustable, when the door becomes wedged or stuck in its casement it is practi cally impossible to open the door without destroying it. My hinge is particularly adapted for the use on refrigerator cars and the like. By its use the door may be slightly elevated and loosened from its casement.

With the above purpose in View my in-- vention consists in certain novel features of constructlon and arrangements of parts, as

will be hereafter more fully described,

pointed out in the claim and illustrated by the accompanying drawings in which:

Figure 1 is a perspective view of the movable leaf and 1 Fig. 2 is a perspective view of the stationary leaf and Y I Fig. 3 is a perspective of the pintle holding the stationary and movable leaves of Figs. 1 and 2 in operative positions and Fig. 4 is a sectional plan of the assembled hinge, the section being taken through the knuckles of the leaves.

Numeral 5 designates the stationary leaf having the holes 6 and the knuckles 7 and 8. In the knuckle 8 is formed a counter sunk portion 9 of the form best illustrated in Fig. 4. In the knuckle 7 is formed a slot 10. Numeral 11 designates a set-screw secured by threaded engagement with the knuckle 7.

Numeral 12 designates a movable leaf 'havtween said knuckles 7 and 8. Numeral 16 Patented Sept. 2'7, 1921.

designates a pintle having a shaft 17 rounded at its external end 18 and having the head 19.

When the movable leaf 12 is positioned so that its knuckle 14 is positioned between theknuckles 7 and 8 the pintle 16 is-dropped through the slot 10, the hole 15 and into the counter sunk portion'9 of the knuckle 8. The diameter of the hole 15 is slightly greater than the diameter of the shaft 17 of the pintle 16. By this means the leaves of the hinge are secured in rotative engagement with each other. The counter sunk portion 9 of the knuckle 8 is of the shape of the segment of a' sphere of substantially larger radius than the diameter of the shaft 17 of the pintle 16.

- The slot 10 in the knuckle 7 is of a width slightly greater than the diameter of the shaft 17 of the pintle 16.

Assuming the stationary leaf 5 secured to the vertical post of the easement of the door of a refrigerator car and assuming that the movable leaf 12 is secured to the door of such a'car and that the leaves are held in rotative position by means of the pintle 16,

it will be seen that by rotating the set screw 11 the pintle 16 will be moved longi tudinally in the slot 10 and the end 18 rotated in the counter sunk portion 9 of the knuckle 8. 'By this rotation, the door will bemoved upward and rotated slightly above the counter sunk portion 9 of the knuckle 8 of the lower'hinge. There will of course be two hinges to the door; that isan upper hinge and a lower hinge.

The weight of the door normally causes the door to sag and this will maintain the pintle in the position against the set-screw shown in Fig. 4.

When the door has been thus moved it will have been loosened from its casement and 1 can be easily opened.

What I claim and mean to secure by Letters Patent is- In a hinge, a stationary leaf having knuckles formedintegral therewith and a slot formed in one of said knuckles, a counter sunk portion formed in the other of said knuckles, a movable leaf having a knuckle with a hole therethrough, a pintle said pintle passing through the slot in said stationary leaf, the hole in the knuckle of said movable leaf and into the counter sunk portion of the knuckle of said stationary leaf, a set-screw operatively secured-to said slotted knuckle so that a rotation of said set-screw will cause a lateral movement of said pintle in said slotted knuckle and a rotation of the end of said pintle in the counter sunk portion of one of said other 10 knuckles. 1

In testimony whereof I aflix my signature.
